What you need before you walk in

A business bank account separates your personal money from your business money, which protects you legally and makes taxes simpler. Most banks will open one for you in a single visit or online session, but they need specific documents first. The exact list depends on your business structure — sole proprietorship, partnership, LLC, or corporation — and the bank's own rules.

Start by gathering your Employer Identification Number (EIN), which the IRS issues free. If you operate as a sole proprietor using your Social Security number, you may not need an EIN, but having one keeps your personal and business finances clearer. You can request an EIN online at irs.gov in minutes, or by mail if you prefer.

Next, bring a government-issued photo ID — driver's license or passport — and proof of your business address. A utility bill, lease, or mortgage statement dated within the last 60 days works. If you work from home, a recent bill with your home address is fine.

Key Takeaways

  • You will need your EIN (or Social Security number if you are a sole proprietor), a photo ID, and proof of your business address before any bank will open an account.
  • The documents required vary by business structure: sole proprietors need less paperwork than LLCs or corporations, which must bring formation documents.
  • Banks typically charge monthly fees ranging from zero to $25 or more, so compare accounts at multiple banks before choosing one.
  • Opening an account online is faster than visiting a branch, but some banks require an in-person visit to verify your identity.

Documents for each business structure

Sole proprietors need the least paperwork. Bring your photo ID, proof of address, and either your EIN or Social Security number. Some banks will ask for a DBA (Doing Business As) certificate if you operate under a name different from your own — check your state's requirements, as some states require you to register a DBA before opening the account.

Partnerships must bring the partnership agreement, proof that each partner has an EIN or Social Security number, and photo IDs for all partners. Not all banks accept partnerships, so call ahead. The account will typically list one partner as the primary account holder.

LLCs and corporations need the most documentation. Bring your Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation), your EIN letter from the IRS, a resolution or certificate authorizing the account (some banks provide a template), and photo IDs for the owner or authorized signers. The resolution shows the bank that the business has approved opening the account.

Choosing between online and in-person

Opening online is faster — you can complete the process in 10 to 15 minutes without leaving your desk. You upload photos of your documents, answer questions about your business, and the bank verifies your identity through a video call or by checking public records. The account is usually ready within one to three business days.

In-person visits take longer but let you ask questions and see the banker's face. Some banks still require an in-person visit to verify your identity, especially if you are opening a corporate or LLC account. Call the bank's business line before you go to confirm what documents they need and whether you can complete it in one visit.

Online-only banks like Mercury, Brex, and Wise often have lower fees and faster setup, but they may not offer the same services as traditional banks — check whether you need a physical branch, a debit card, or a business credit line before you choose.

What banks will ask about your business

The banker will ask what your business does, how much money you expect to move through the account each month, and whether you plan to accept credit card payments or checks. Be honest about your revenue projections — banks use this to flag accounts for money-laundering risk, not to judge you. If you say you will move $500,000 a month but your business is a freelance writing practice, the bank may freeze your account later when they notice the mismatch.

They will also ask whether you have other business accounts, whether you have been denied a bank account before, and whether you have any criminal convictions. Answer truthfully. Banks run background checks, and lying disqualifies you immediately.

Monthly fees and account features to compare

Business checking accounts charge monthly maintenance fees that range from zero to $25 or more, depending on the bank and account type. Some banks waive the fee if you keep a minimum balance (often $1,000 to $5,000) or if you set up direct deposit. Others charge per transaction — per check written, per deposit, per wire transfer — so calculate what you will actually use before you choose.

Compare what is included: unlimited check writing, online bill pay, mobile deposit, wire transfers, and ACH transfers (electronic transfers between accounts). Some banks charge extra for wires or limit the number of free transfers per month. If you plan to accept credit card payments, ask whether the bank offers merchant services or can refer you to a processor.

Also ask about overdraft protection and what happens if you go negative. Some banks automatically transfer money from a linked savings account; others charge an overdraft fee of $25 to $35 per transaction.

The timeline from documents to first deposit

Online accounts are usually ready within one to three business days. In-person accounts at a branch can be open the same day, though the debit card and checks may take five to ten business days to arrive by mail. Ask the banker when you can start using the account — some let you begin immediately with a temporary card or checks, while others make you wait for the physical card.

Once the account is open, you can deposit money by mobile check deposit (if the bank offers it), in-person at a branch, or by ACH transfer from your personal account. Ask whether there are deposit limits on mobile deposits — many banks cap mobile deposits at $2,000 to $5,000 per day or per month when you first open the account, then raise the limit after 30 to 60 days of activity.

Common reasons banks deny business accounts

Banks may deny your account if you have unpaid tax liens, a history of bounced checks, or prior accounts closed for cause. They also deny accounts for businesses in high-risk industries — cryptocurrency, gambling, money services, and some types of lending face extra scrutiny. If your business falls into one of these categories, ask the bank upfront whether they accept it before you gather documents.

If you are denied, ask why in writing. Some banks will reconsider if you address the issue — for example, by paying off a tax lien or waiting a year after a prior account closure. Other banks have blanket policies and will not budge. If one bank says no, try another; policies vary widely.

Frequently Asked Questions

Can I open a business account with just my Social Security number?

Yes, if you are a sole proprietor. You do not need an EIN. However, getting an EIN is free and takes minutes online, and it keeps your personal and business finances more clearly separated for tax purposes and liability protection.

What if I do not have a physical business address yet?

Use your home address. Banks accept residential addresses for home-based businesses. If you use a virtual office or mailbox service, call the bank first — some accept them, others do not.

Do I need a business license to open a business bank account?

Not always. Banks care about your EIN or Social Security number, not your license. However, some states require a business license before you can get an EIN, so check your state's rules. If you do not have a license yet, you can usually still open the account.

How long does it take to get an EIN?

Online requests are instant — you receive your EIN immediately after you submit the form at irs.gov. Mail requests take four weeks. If you need the account quickly, apply online.

Can I use a business account for personal expenses?

Legally, no. Mixing personal and business money weakens your liability protection and complicates taxes. Keep them separate, even if it means opening two accounts.
